Description

This is the Givens rotation method in Golub's "Matrix Computation". The c=cos(theta) is not always positive. By contrast, c=cos(theta) in Matlab's approach is always positive. But the results are still correct.

Reference: Golub and Van Loan, "Matrix Computation".

MATLAB release MATLAB 6.5 (R13)
